M ETALLIC FENCING.

SPECIFICATION forming part of Letters Patent No. 485,741, dated November8, 1892.

Application filed May 10, 1892. Serial No. 432,428. (No model.)

To all whom it may concern:

Be it known that I, HIRAM A. HARRINGTON, of Anoka, in the county ofAnoka and State of Minnesota, have invented certain Improvements inMetallic Fencings, of which the following is a specification.

My invention relates to improvements in metallic fences; and its objectis to provide a simpler, a cheaper, and a stronger system ofintermediate supports for the wires of metallic fences, therebydispensing with at least half of the metallic posts ordinarily employed,and at the same time furnishing a fence fully as strong and durable asthose heretofore constructed and of a much better appearance.

The invention consists, in general, in the constructions andcombinations hereinafter described, and particularly pointed out in theclaims.

The invention will be more readily understood by reference to theaccompanying drawings, in which- Figure 1 shows a section of fenceembodying my invention. Fig. 2 is an enlarged perspective View of one ofthe main supplementary supports. Fig. 3 is a perspective view of one ofthe vertical tie-slats. Fig. 4 is an enlarged cross'section on the linea: m of Fig. 2. Fig. 5 is a vertical section taken through the base ofthe metallic post and showing means for holding the same againstrotation. Fig. 6 is a plan View of the circular groundplate or base ofthe post.

As shown in the drawings, 2 2 represent posts arranged at a distance ofabout fifty feet apart and made up of sheet metal, in conformity with myapplication numbered 407,011, dated September 23, 1891, and filed in theUnited States Patent Oflice October 1, 1891, and allowed February 23,1892. The several wires 3, which may be of any number, are strung uponthe posts and are supported at intermediate points, preferably at aboutevery ten feet, by the uprights 4, having the baseplates 5. Theconstruction of one of these of these loops are bent inwardly to an apex10, and from thence coiled tightly about one another, as shown at 11.One wire loop is short and has its upper ends soldered at 12 to thewires of the other loop, which loop has thelongupwardly-projectingstrands13,which pass up through the curled part 14 ofthe plate or strip of sheet metal 4, this construction being mostplainly shown in Fig. 4. At the top the wires have their ends 15 bentaround the top wire 3 of the fence, thus holding the plate or strip 4 inplace. At the bottom the tongue 16 of the strip is curled about thelower wire of the fence to fasten'the same, and the intermediate wiresare fastened upon the strips by the short wires 17, which pass throughholes provided therefor in the strip 4, and have their outer ends coiledtogether to firmly support the wires 3. The base of each support issecured upon the ground by two pegs 18, having the hooked upper ends 19and driven crosswise down through the slots or notches 6, the hooksengaging the lower ends of the main loops of wire. Between each pair ofthe supplementary supports I preferably provide one or more of thevertical slats 20. The slats are made up in much the same manner as theupper part of the supplementary support, each consisting of a strip ofsheet metal having its edges formed about two vertical wires 23, theupper and lower ends of which are bent around the top and bottom wiresof the fence. The intermediate wires are each fastened by a single loop24 of soft wire, extending through the metal strip 21. When constructinga fence of this pattern, much annoyance has been occasioned by thetwisting of the metallic post 2 upon the threaded studs 25 of theground-fork 26,upon which the post is secured by the two internalcross-bars 27. To obviate this twisting, I place beneath the lower end28 of each post an iron base-plate 29, having the annular groove 30,provided with the ratchet-teeth 31, and on the lower end of the postarrange the gravitypawls 32 to engage the ratchets and thereby preventthe posts from becoming loose. On the inside of the plate is an annularcollar or shoulder 33, to fit Within the post and prevent the loweredges of the same from being indented.

Having thus described my invention, I claim as'new and desire to secureby Letters Patent- 1. The combinatiomwith the main posts, of the Wiresstrung thereon, the supplementary supports having the fiat sheet-metalbases 5, means for securing said bases on the ground, and means forattaching the wires to the upper parts of said supports, substantiallyas described.

2. The combination, with the main posts and the wires strung thereon, ofmetallic slats consisting of the strips 21, the vertical wires 23embraced thereby, the ends of .said wires beingsecured upon thefence-wires, and means for attaching the intermediate fence-wires tosaid strips, substantially as described.

3. The combination, with the fence-wires, of the supplementary supportsconsisting of the metallic strip 4, the two metallic loops 8 and 9, theupper ends of one of said loops being embraced in the curled edges ofsaid strip, the curled lower end 16 of the strip, said loops twistedabout one another, the plate 5, secured between the lower ends of saidloops and having the notches, and the metallic pegs 18, extendingtherethrough and having the hooked ends, substantially as described.

at. The combination, with the wires 3, of the strip 1, the short loops17 for fastening the wires thereon. the main loops 8 and 9, twistedtogether at 11 and having the straight lower sides, said loops solderedat 12, the metallic base-plate 5, having the curled edges 7, the

hooked pegs to secure the base and the lower end of said loops, theupper ends 13 of one of said loops embraced by the curled edges of thestrip 4, and means for securing the top and bottom wires thereon,substantially as described.

5. The combination, with the base of the metallic post, of a verticalfastening therefor, the base-plate 29, having the ratchet-feet 31, andthe gravity pawl or pawls 32,provided on the post to engage the same,substantially as described.

In testimony whereof I have hereunto set my hand this 4th day of May,1892.

I-IIRAM A. HARRINGTON.
